Now, I know that the subject here is sexual arousal, but since I've already mentioned Plato and he is so relevant to the subject of Eros – and was probably sapiosexual himself — I think it's worth stepping briefly into the realm of philosophy.

You see, for a true geek there's often little difference, because when you engage our brains, which are connected to our genitals, it often turns on our lust response (we're quite often sapiosexuals - people who lust after intellect first), but it's the *brain* you aim for, the intellect, to turn us on, not our genitals.
